|You aren't getting very good results with this.
This lens should be reasonable at f/5.5 even with a 15 megapixel sensor, but your samples aren't showing good performance.
This one seems to be behaving more like the 400mm Telemegor, which isn't great.
I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work.
